What is the Difference Between Analog Computer and Digital Computer?
Along with the functions of these two types of computers, there is a lot of other difference between these two. Here, let us discuss the difference between analog computer and digital computer in the table given below.
Key Difference Between Analog Computer and Digital Computer
|Analog Computer||Digital Computer|
|The speed of these computers is low.||Digital computers are relatively faster.|
|Continuous values are used in analog computers, and these systems handle continuous data.||These sorts of systems process discrete data or deal with discrete values in digital computers.|
|It depends upon physical variations.||It does not depend upon physical variations.|
|Analog computers provide less accurate results.||Digital computers provide more accurate results.|
|They have high power consumption.||They have low power consumption.|
|They are used in engineering and scientific fields.||These are used in almost every field.|
|Analog computers are not easy to use.||Digital computers are easy to use.|
What is an Analog Computer?
An analog computer system is a very ancient computer system that operates on mathematical variables in the form of constantly changing physical quantities/entities. They work on analog signals because they employ continuous values rather than discrete values. These computers were utilized for the first time in the 1950s. Analog computers are restricted in their ability to tolerate issues and can never be exceedingly precise.
An analog computer is a form of computer that operates constantly, regardless of the input fluctuations. Instability in current, temperature, electric, and mechanical parts are examples of these variances. Thermostats and thermometers are the greatest examples of analog computers.
Characteristics of Analog Computers
Analog computers are used mainly in Engineering and Scientific applications. Let us check the characteristics of analog computers are listed below.
- They have high power consumption.
- They are less reliable than digital computers.
- These computers use signal generators and a network of resistors and capacitors.
- They have very low or limited memory.
- The speed of analog computers is comparatively low.
What is a Digital Computer?
The digital computer is a type of computer that accepts and computes binary-formatted data. The digital computer also receives and processes data in a distinct fashion. As a result, the input might be made up of characters or binary numbers.
The binary code is made up of two digits: 0 and 1. The digital computer can perform various tasks just by manipulating and counting these digits. Supercomputers, Personal computers, and Minicomputers are all examples of digital computers.
Characteristics of Digital Computers
Digital computers operate on data in binary codes, using only two digits 0 and 1. By using these digits, digital computers can perform various activities and regulate operations. Further, let us check the characteristics of these computers mentioned below.
- They have huge memory and can store a large amount of data.
- They produce numbers as outputs.
- These computers have low power consumption.
- They are more reliable than analog computers.
